Johnson Pressure Switch Complete 2.1 Bar

Always keeps your pressurized water pump at the correct pressure: This original Johnson Pump pressure switch automatically turns the pump on and off as soon as the water pressure in the system falls below or exceeds the set limits. A worn or defective pressure switch is often the reason why the pump runs continuously or doesn't start at all – with this spare part, you'll be back at sea in no time.

Before replacement, release the water pressure in the system and disconnect the pump from the power supply. Teflon tape on the thread of the new switch ensures a permanently tight connection.
